"I was impressed with the build quality of these two drive enclosures. They are reasonably durable and should have no issue safely containing drives. Their solid anodized aluminum shells are not bad to look at, either. The ICYRaid has simple hardware RAID features easily selected by a rear panel switch, making configuration a no brainer. The ICYCube only operates as a JBOD unit, meaning those desiring RAID are going to have to rely on software-RAID features of their OS (as well as the corresponding performance hit when using a software RAID through a single external interface link)."
"I really like the Icy Dock in so many ways; the design has been thought out and everything just works. The Icy Dock is aimed at users who want fast external storage, combined into a unit that is sleek, subtle and well designed and on all counts the Icy Dock delivers. It is compatible with both PC and Mac and even comes with a 3 year warranty for peace of mind."
"The Icy Dock offers a lot of value with its aluminum metal enclosure and cooling fan to prevent installed drives from overheating. The aforementioned appearance is good at the price point, though it could be improved with some more premium parts for the front bay doors and the rear panel. The switches are a bit tough to get to, but that's really for the drives' safety and shouldn't be held against Icy Dock. What really stands out though is that by providing users with the ability to configure their drives in RAID modes, performance gains are can be had without shelling out a lot of cash. In RAID 1, users should expect near identical performance to what a single drive would provide, and the HGST drives we installed proved that point. On the other hand, RAID 0 should offer double the performance. In our testing, the drives didn't quite achieve that 2x mark, however they were over 1.5 times quicker. Interfacing over USB 3.0 likely created a bottleneck limiting full enhancement. Overall, the gains in RAID 0 are solid, and the security offered by RAID 1 offers users an inexpensive backup option"
"The Icy Dock ICYRaid MB662U3-2S, unlike other external USB 3.0 enclosures has the hardware capability to run drives in RAID, independent of the PC. The ICYRaid MB662U3-2S replaces the discontinued MB662UEAB-2S which used the older USB 2.0 and FireWire connection with a much faster and more widely used USB 3.0 port. Users can install a pair of two 3.5” HDDs up to 4TB in capacity each for a total of up to 8GB of storage inside the Icy Dock MB662U3-2S. To cool both drives when they are continuously used, the ICYRaid MB662U3-2S is equipped with a 40mm Sunon MAGLev fan that operates silently and can be adjust through a built-in fan controller. Users can configure drives installed inside the MB662U3-2S in RAID 0, RAID 1, BIG, or JBOD just by simply moving the RAID toggle switch and pressing the reset button while the enclosure is on. No further steps are required, other than formatting the drives or adjust the partition when necessary of course. The Icy Dock ICYRAid MB662U3-2S is compatible with either Mac or PC and comes with a three-year limited warranty."
"With the bays open installation of a hard drive is simple. Just slide it in and close the door... perfect and the fact that even the latest SATA3 4TB models are supported is great.
Keeping things super easy ICY DOCK have done well to keep the device configuration to a hardware level. Rather than have to mess about in a BIOS, or application, we simply turn to the back of the unit and move the switches to the mode we want. The ability to enable/disable power LEDs and power saving is a nice bonus and we like that the fan speed can be varied.
We see the benefits of USB 3.0. Even with a single drive the ICYRaid easily exceeds the 35MB/s limit of most USB 2.0 ports by some way. When we combine drives in RAID0 for maximum performance the figures scale nicely and there are few external enclosures which can compete with this speed, flexibility and build quality."
